Usina A. The Near-field Methods Development of Radiation Systems Characteristics Determinarion Using Broadband Signals

Object - restoration of radiation systems characteristics in frequency band. Aim - development of near field methods determination of radiation systems characteristics using broadband signals. Research methods - geometrical diffraction theory, theory of accidental functions, statistic antennas theory. The task of methodical errors determination is solved, for the first time are got analytic expressions for statistic description of complex transmission function of radiation system, is worked up methods of resulting error estimation of near field methods of radiation systems characteristics restoration in frequency band. Is worked up a determination method of amplitude and phase distribution of phase grates on by amplitude measuring of dynamic near field. Sphere of use - connection, researches of radiation systems, medical researches.
